Question

Anita is running to the right with a speed of \(6.0 \mathrm{~m} / \mathrm{s}\), as shown in the figure. Balls 1 and 2 are thrown toward her by her friends (standing still on the ground). As measured by Anita, both balls are approaching her at a speed of \(11 \mathrm{~m} / \mathrm{s}\).

You may assume all the motions are completely horizontal.

a) According to her friends, what is the magnitude and direction of the velocity of ball \(1\left(\vec{v}_{1}\right) ?\)

b) According to her friends, what is the magnitude and direciton of the velocity of ball \(2\left(\vec{v}_{2}\right)\) ?
